What is the life expectancy of a child with fragile X syndrome?
Life expectancy for people with fragile X syndrome is generally normal. Many affected people participate in an active lifestyle and have good health. Some people are more prone to a number of medical problems, such as ear infections and/or seizures .
Does everyone with Fragile X have autism?
Almost 50 percent of men and 16 percent of women with fragile X also have autism, according to the U.S. Centers for Disease Control and Prevention. Other studies have hinted that up to 90 percent of men with fragile X have some autism traits, such as a tendency to avoid eye contact2.
Do children with fragile X talk?
Most children affected with fragile X syndrome will have some form of speech/language delay. Because they do not speak in short phrases until 2 1/2 years of age, these children are often referred to a speech/language pathologist before a diagnosis of fragile X is made.

What is the number one cause of autism?
We know that there’s no one cause of autism. Research suggests that autism develops from a combination of genetic and nongenetic, or environmental, influences. These influences appear to increase the risk that a child will develop autism.
Which gene causes autism?
Inherited mutations in a gene called ACTL6B lead to autism, epilepsy and intellectual disability, according to a new study1. The mutations are recessive, which means that they lead to autism only if a person inherits them in both copies of the gene — one from each parent, who are silent carriers.
Can autism be seen in eyes?
A new eye scan could help identify autism in children years earlier than currently possible.
How does autism run in families?

What does it mean to be a carrier of Fragile X?
People can be carriers of Fragile X syndrome without having the condition themselves. This means they have a type of Fragile X gene that they can pass on to their children. Male and female carriers of Fragile X can develop Fragile X-associated tremor/ataxia syndrome (FXTAS) when they’re over 50 years old.
How does fragile X affect a child’s learning?
Children with Fragile X can find it hard to understand and process information. These difficulties mean they can have problems with learning, behaviour and development. Children with Fragile X can also have autism spectrum disorder-like behaviours.
